Abstract: A sound reproducing method used in sound reproducing apparatus that includes the steps outlined below is provided. A sound signal is generated with a 3D sound generating process according to listener data and sound data. Pre-recorded sound data is retrieved to further generate a target distance function corresponding to the sound distance. A fixed head-related transfer function corresponding to a fixed distance is retrieved. A target head-related transfer function corresponding to the sound distance is generated by adapting the target distance function to the fixed head-related transfer function. The sound signal is reproduced by multiplying the sound signal by the target head-related transfer function.

Abstract: A method for obtaining Hi-Res audio transfer information is provided. The method is applicable to the electronic device having a processor. In the method, a first audio signal is captured and converted from the time domain into in the frequency domain to generate a first signal spectrum. Then, a regression analysis is performed on an energy distribution of the first signal spectrum to predict an extended energy distribution according to the first signal spectrum, and head-related parameters are used to compensate for the extended energy distribution to generate an extended signal spectrum. Finally, the first signal spectrum and the extended signal spectrum are combined into a second signal spectrum which is converted from the frequency domain into the time domain to generate a second audio signal including Hi-Res audio transfer information.

Abstract: A sound reproducing method used in sound reproducing apparatus that includes the steps outlined below is provided. A sound signal with a three-dimensional (3D) sound generating process is generated according to listener data and sound data. Whether a sound source position is within a target region relative to a listener position within a virtual environment is determined according to the listener data and the sound data. The sound signal is multiplied by an adjusting function to enhance peaks and valleys of the sound signal while maintaining a behavior of the sound signal when the sound source position is within the target region. The sound signal is reproduced.

Abstract: An online video and audio broadcasting system and method are disclosed. The online video and audio broadcasting system includes a first verification module, a second verification module, a management module, and a play module. The first and the second verification module is connected to a primary verification system and a backup verification system to correspond to a first set of digital rights and a second set of digital rights, respectively.
